The skill and the precision of the Anasazi, ancient inhabitants of the Southwest, in measuring the movements of the Sun and Moon is evidenced not only at Chaco Canyon but at a number of other sites.

A. in measuring the movements of the Sun and Moon is evidenced not only at

B. in measuring the movements of the Sun and Moon are evidenced not only at

C. in measuring the movements of the Sun and Moon is evidenced at not only

D. to measure the movements of the Sun and Moon is evidenced at not only

E. to measure the movements of the Sun and Moon are evidenced not only at

What is the problem in E?

Thanks.

In this context, COMMA has been used to separate no-essential modifier. So, the rule "COMMA + Infinitive" is not applicable.

I think E is an awkward structure.

Example:

We don't say:

His efficiency to work...
Their skill to play.....
My expertise to teach..

We say:

His efficiency in working....
Their skill in playing.....
My expertise in teaching....

I am interested to know what the experts think about the option E.

Thanks.

Hi atulmangal,
I doubted on choice E, because, as gmat_perfect said, we can use use COMMA here, as comma is used to separate the appositive - this is also what I thought.

I read this comma+infinite rule in this forum recently, so you can search for it or I will share the link later (don't have it right now).

Moreover, there is one rule which I want to mention,
we should NOT use INFINITIVE OR PARTICIPLE form of a verb if we have a noun for it.

But as here we are using gerund, I am confused.

@Gmat_perfect

if possible with an example so that i understand better what are essential and non-essential modifiers.

Thanks

I'd have cast it as a simple idiom issue -- you have skill in, but ability to, or capacity for, et cetera.

i agree with JIM that the way to deal with this one particularly was easier from the idiom perspective...i straightforward went for B

Yes; just that if it helps, adjectives (skill and precision in this case) are in general followed with "Gerunds". (measuring in this case);

In only some cases when adjectives describe mental state, can adjectives be followed with "infinitives" (to measure as used in E) as well. Some such adjectives which are followed with infinitives are Sad, Happy, disappointed etc.

Example: I am happy to announce that the truth has finally prevailed.
